Is it permissible to pay university installments to the new oppressive government, and is that considered assisting them in their oppression?

The questioner must pay the agreed-upon expenses to the university, even if it is in an infidel or oppressive country, because a Muslim is commanded to fulfill contracts with everyone. It is forbidden to expose the wealth or lives of the people of a belligerent country (Dar al-Harb) if a Muslim enters their land under a covenant of security or truce. The questioner can leave this university and search for another in a more just country.
